Divided and this application filed December 1, 1927. Serial No. 236,984.

My invention relates to typewriting or like machines and to so-called billing mechanism for such machines. The present invention involves improvements on the construction disclosed in my Patent No. 1,650,351, dated November 22, 1 927. and is a division of my application, SerialNo. 143,382 filed October 22, 1926, now Patent No; 1,825,148, dated Sept. 29, 1931. v

The object of the present invention, generally stated, is to improve my prior pat ented construction and to facilitate the handling and control of work sheets used therein. More specifically stated, the objects of the present invention are as follows:

(1st) To provide means for automatically locking the paper feed rollers which coact with the register sheet in inefiective position;

(2nd) To provide an improved manner of mounting the set of feed rollers which coa'ct with the register sheet;

(3rd) To provide means for supporting the ledger sheet in a manner which will more readilv facilitate the introduction of a comparatively thin bill or statement sheet;

(4th) To provide adjustable means for determining the normal position of the double deflector; and

(5th) To provide an improved side edge gaging means on the spindle or shaft for the feed rollers of the register sheet.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

My invention is shown in the present in-v stance embodied in a Remington front feed bookkeeping machine, but I have only shown so much of said machine as is necessary to illustrate the invention in its inclusion therein. It should be understood, however, that the invention is not restricted to embodi ment said machine, but is of general application wherever found available.

As in themachines hereinbefore referred to the present machine is capable of a wide range of uses in connection with various so: called billing operations and the like, where two or more work sheets are to be correlated in the'machine and printed 'ata single operation. However, I do not deem it necessary to describe specifically the many difi'erent forms of billing operations in which the machine may be used. It is suflicient for an ui'idcrstanding of the present invention to specifically describe one mode of billing that may be successfully carried out with the aid of the present machine, and perhaps briefly 'refer to some of the'various other methods inconnection with which the machine may.

ledger sheets. In the example referred to the register sheet and its accompanying carbon sheet remain in the machine. Means are provided to enable the ledger sheet and itsaccompanying carbon sheet to be quickly introduced and properly positioned to receive the requisite entries without disturbing the "previously introduced register sheet and its companion" carbon sheet. Means also are providedfor then quickly entering a statement sheet into the machinein front of the platen and accurately positioning it in prop er correlation with the previouslyintroduced ister sheets; If desired,ladditionalentries ncompanion carbon sheetand another ledger ledger sheet andthe printing line. The entriesmay then'be made on the statement sheet, and these will be transferred through the interposed carbon sheets to the ledger and regmay-belmade onthe ledger sheet which are not to appearonthe statementor register sheet. The statement and ledger sheets are then rapidly withdrawnfrom the machine without disturbing" the register sheet and its sheet and statement sheet may then be quickly introduced, as before, andso on.

return of the carriage after writing a statement and making the corresponding entry on theledger and register sheets, advances the register sheet in position to receivethe manifold copy of the next entry on the register sheet. I

With the foregoing general explanation of theipurpose and operation, I will proceed to describe the invention as it is embodied, in the present instance, in said hereinbefore mentioned Remington machine.

' "The frame of the machine includes the usual top plate 1 supporting fixed guide rails 2. The carriageor truck comprises front and rear guide or cross barsz3, united by end bars 4 and 5. The uide rails 2 and cross bars 3 are opposite y groovedto receive crossed anti-friction rollers ,6, by which the carriage is v supported in the usual manner to travel from side to side of the machine over the top plate 1. r

'A cylindrical platen 7 is mounted in the usual manner in a platen frame comprising the rigidly connected end plates 8 and 9; the platen frame being connected to the car:

which surround it, against the upper-case limitingjstops14. This brings the printing line on the platen to arposition where the uppermost types on the usual type bars will re ister therewith.

j here are two curved paper deflectors and 16 employed beneaththe platen, onearranged above the other and maintained w spaced a art by intermediate, spacing members or locks'17 and 18 located near the ends thereof. Generally speaking, these de flectors conform to the curvature of the platenor are substantially concentric therewith length ofthe platen. As thus constructed and extend substantially throughout the there are two separate channels provided, one

of which is the open channel 19 between the two deflectors. and. which is bounded at its sheetsintroduced, into the channel 19. The

other separated channel 20 is provided between the under surface of theplaten and the up er deflector 15. The forward edge of the :de ector 16 terminates in advance ofthe for:

wardedge of the deflector 15, and has a slight 'downwardcurvein" cross section. The deflector 16 is continued up at the rear toform anupwardly and rearwardly extending paper table 21'whi'ch terminates at a consider- Aline spacing operation, effected. by the 8 and 9 of the platen frame. In this manner the rigidly united deflectors 15 and 1 6 are mounted on the rod '23 andmay have a slight pivotal movement thereon. .A light wire spring 24 (Fig. 9) is connected by screws 25 and 26 to a cross bar 27 of the platen frame, the spring being anchoredat one end 1 V on the screw 25 and coiled around the stem of the screw 26. The upper free end ofthe spring 24 1s looped at 28, where itbears upward against the bottom ofthe deflector 16 and causes the forward edge portion of the deflector'15'normally to be lightly pressed against the platen, or against the interposed work sheet. 'In this manner the sheets introduced from the'rear of the platen through the channel 20 will'be held snuglyagainst the platen, and thesheets introduced into the channel 19 w1ll be prevented from entering 1 the channel 20. By moving the upper end if of the paper table forward, the forward end portions of the deflectors may be moved downward a limited distance, thus carrying the forward contact edge of the deflector away from the platen. Unlessthis contact of the deflector 15 with the platen is nicely regulated and controlled, there is apt to be an undue binding of said deflector on the platen, or on the register sheet, during the forward turning of the platen.

In accordance with the present invention I have provided adjustable means for determining the normal position of the double deflector on its pivot 43, and also for determining the limit of pivotal movement that said double deflector may receive away from normal position, which will now be described.

It will be seen that a cross bar or supporting'rod 29 is connected at its ends to the or c plates 8 and 9 of the platen frame, and is fixed thereto against turning movement. One, or more sleeves 30 are mounted on'this rod, two being shown in the present instance. Each sleeve is tapped transversely throughout its d ameter in two lines at right angles to each other, so as to provide a plurality of tapped openings 31. In the most convenient one of these openings is received a set screw 32 that is adapted to bear at its a. inner end againstthe supporting rod 29.

Fixed to each sleeve 30 is a snail-cam 33, the curved contact edge of which is adapted to form a bearing against which the back of the paper table 21 is pressed by the spring 24;, thus determining the normal position of the double deflector on its pivot and preventin the forward ed 'e of the deflector 15 from bearing with undue force against the platen. By a turning adjustment of the cams 33 around their supporting red, the position of the forward edgeportion of the deflector 15 with referen e to the platen may be nicely regulated, the screws 32 holding the cams in the positions to which they are adjusted.

In order to limit the pivotal motion of the double deflector in the opposite direction, I provide one or more additional adjustable snail-cams or stop devices 34 (see Fig. 3) to contact with the bottom of the deflector 16. The carriage of the Remington machine, as manufactured, has on its cross bar 27 a series of faced lugs 35 located near the ends of the bar each of them being tapped foreand-aftof the machine. In the present stance, I make use of two of these tapped openings to receive the stems of headed binding screws 36. On each of these screws is supported one. of the cams 3a. slightly l'oosen ingeach of the screws 36, the associated cam or stop 34 may receive a turning adjustment around the stem of its screw to bring the curved contact ed 'e of the cam or stop closer to or further from the bottom of the deflector 16, and thus regulate the extent of releasing motion of the double deflector.

lVhcn the cams 34 are adjusted to the proper position, a tightening of the screws 36 will hold the cams with a binding action in such position.

In some instances it may be found desirable to hold the double deflector rigid in its adjusted position, with the forward end of the deflector 15 a definite predetermined distance from the platen. This may be readily atta' this time the spring 2a is ineflective and desired may be dispensed with. It will be therefore, that the adjusting cams 33 and 3 1- are cite i ve from either point of view or condition pointed out above.

It is intended at times to introduce rearwardly through the channel 19, first one. comparatively heavy ledger sheet L (see Fig. 8), and then a comparatively thin or light state ment saeet S. Ordinarily tne tendency of the lirst introduced curved and relatively wider ledger sheet L is to spring or force itself towards the bottom of the channel 19, or against the upper side of the lower deflector 16. It follows, therefore, that theledger In order to overcome this dfsadvan- 'e l have provided, by the present inven- 10 11, work sheet supporting means in ne channel 19 for supporting the led er sheet in uno. structnig position in said channel,

where it will not interfere with the ready insertion and tree passage through the channel of another work sheet, such as the statement sheet, clearly indicated in Fig. 8. Such means in the pr sent instance comprises a pluof work-supporting members or ribs carried by and projecting upward from the contact face of the deflector 16, in the channel 19. As shown, there are two of these supporting members or ribs 37, having a parallel arrangement and extending fore-and-aft of the mac zine through the channel 19 and terninating 38 near the top of the paper table 21. The thickness of each rib 37 is preferably such that, within its field of operation in the channel 19, it occupies preferably about onethird of the space between the two deflectorslo and 16. The'ri s may be located at appropriate points longitudinally of the platen, and be properly spaced apart, in order to leave an intervening spacebetween them. Through this intervening space a work sheet 5- 8) may pass free from obstruction the channel 19, while another work that they may be adjusted to (life is supported on the upper contact in orderthat various widths of sheet S may be introduced between said ribs in thechannel. 19. Any'suitabl'e means may be employed" for this purpose. In the present instance, I provide three parallel series of openings 39 V in the deflector 16 and paper-table 21 for each of the ribs. The vdifferent series of openings for each .rib' are spaced'apart longitudinally of the platen about three quarters of an inch.

' A series of screws 40 pass through a series of openings 39 and are rece ved at their threaded ends in tapped openings in a companion rib, to detaehably secure each rib in anyone of the three'positlonsto which it may be adjusted along the channel 19. It has been found in practice that the means described effectively overcome the diiliculties g7 downwardly and rearwardly inclined efective position, shown in dotted lines in said figure, and vice versa, as disclosed in my said patent. I In. order to receive these movements .the'defiector is constructed and mounted, in the present instance, in the specific manner -disclosedin the application of S. L. Walsoe filed September 2, 1926,.Serial Nor-133,228, nowPatent No; 1,663,362, dated March 20,

As. disclosed in my original application,

" Serial No. 143,382, now Patent No. 1,825,148, 1 means areprovided, whichit is unnecessary to show for the purpose of the present invention, for automatically shifting the deflector 41 into and out-of effective position. hen

I this deflector is in the dottcdline eflect'lve position, shown in Fig. 1, it overlaps andvirtually forms a continuation ofthe deflector 16. In the movement otthe deflector 41 to effective position it passes from a position whereit is out of the path of the type bars to I a position where it is in the path thereof and crosses the printing line, where it is effective in directing work sheets UltlOdHCGd rearward from in front of the platen downward into I the open channel 19. From thence the sheets. I V

' relative movement between the arms44 is determined by the extent of lost motion of 7129' 1 the pins 47 intheir respective slots 48. When, ,g 1 e platen through the channel 20.

' rollers 42 coact with said sheets after the question pass around and beneath the platen to the rear thereof.

The paper feeding mechanism embodied in the present construction includes a plurality of aligned paper feed rollers 42, arranged p to coact with the top of the platen and with worksheets introduced from the rear of the Said feed latter have passed above and beyond the printing lines. The paperfeed rollers 42, as shown in the present instance, are constructthe spindle in its bearings. This is preferred ed and. mounted in thesame general manher as in my said hereinbefore mentioned patent, except for changes in mounting the spindle on which said feed rollers turn, as will presently appear, ,Thus, the feed rollers are mounted for longitudinal adjustment along a supporting rod or spindle 43, supported at its ends by forwardly ex,- tending arms 44' that arepivoted on the supportingrod '29, hereinbefore referred to,

which is secured at its ends to the platen frame. Springs exert their force against the arms 44and thus cause the feed rollers 42 to bear against theplaten, or certain only of the work sheets thereon. By swingin the spindle'or bail 43 upward and rearwar the said feedrollers are released. r In accordance with my present invention I provideeach' of the arms 44 with an inwardly projecting bearing member 46, shown in detail inFi'gs. 6 and 7, in which the ends of the spindle 43 are loosely seated, as shown, the diameter of the bore of each hearing being greater than the diameter of the spindle. This is in or'derthat there may be an equalization of pressure exerted from the individually acting springs 45 on opposite ends of the roller supporting spindle 43. Although it is desirable to thus looselysupport the spindle 43 at opposite ends, so that said {spindle may assume varying angular relations relatively to the axis of the platen as well as a parallel relation thereto,iit also, is desirable to prevent or limit the turning movement of because, among other reasons, I mount sideedge'paper gages on thespindle 43, as will presently appear, and any material turning of the spindle which would displace said gages from efi'ective position should beprevented.

Therefore, I provide each end portion of the spindle with a cross pin 47projecting from opposite sides of the spindle intorslots 48 extending longitudinally of the companion bearing member 461and through the walls I thereof. The diameter of each pin is preferably slightlyless than the width of the slot 48 in which it is received This construction'aiiords a slightrelative pivotal move ment between the arms 44 so that there may be an equalization of pressure ofthe springs 45 on the feed rollers 42 at the-opposite ends 1 of the spindle 43. The extent of-this slight shifting the feed rollers42 away from the laten the arms 44 will shift in unison when the slight'extent of lost motion of the pins 47 in their slots 48 is taken up. Each bear- 5 44 and engages a nut on the opposite side thereof.

In the present construction I have provided means for automatically locking the feed rollers 42 in ineffective position when they are thrown oif. Referring more particularly to Fig. 1, it will be seen that the left-hand arm 44 carries an outwardly projecting headed pin 51. The stem of this pin passes through a curved slot 52 in a locking member or latch 52-3, pivoted on a headed pivot screw 54 threaded into a tapped opening in the end plate 8. The curvature of the slot 52, when the latch is in the fulldine position, is substantially concentric with the axis of the rod 29 on which the arms 44 turn. Extending at an angle to the slot 52 at the upper end thereof is a locking notch 55 that provides a locking shoulder 56. A leaf spring 57 is secured at one end by a screw 58 to the end plate 8, whereas the free end of said spring extends beneath a shoulder 59 on the latch 53. The force of this spring is exerted to shift the latch from the full to the dotted line position when the left-hand arm 44 is shifted to the dotted line position torelease the feed rollers 42. The effect of this movement of the pivoted latch to the dotted line position is to bring the locking shoulder56 beneath the pin 51, and positively hold the feed rollers 42 in the released position against the action of their springs 45. The latch 53 terminates at its upper end in a finger piece 60 by which the latch may be swung forward from the dotted to the full-line position, thereby releasing the pin 51 and enabling the feed rollers to be returned to normal position by their springs 45.

The automatically operating latching means described above leaves both hands of the operator free to adjust the register sheet and its accompanying carbon sheet when the feed rollers 42 are released.

In the present construction I have provided two independent side edge gages 61 and 62 which are mounted on the supporting rod or spindle 43, as shown in Figs. 1 and 2. Each gage is fixed on an independent hub or carrier 63, tapped to receive a set screw 64 by which it is held in any position to which it may be adjusted along the spindle 43 on which it is mounted. The gage 61 projects rearward from the supporting spindle for cooperation with the left-hand side edge of work sheet introduced into the channel 20 from the rear of the platen, whereas the gage 62 extends forward from the spindle where it coacts with the lef -hand side edge of a work sheet introduced from in front of the platen in the channel 19. The spindle 43 being fixed against appreciable turning movement in the arms 44, will hold the gages from unduly turning around the axis of said spindle, when the gages are held in place by the set screws 64. Nevertheless, the gages swing with the spindle when the latter is turned with the arms 44 around the axis of the supporting rod 29 to releasing position. It will be understood that by making the gages 61 and 62 relatively adjustable they may be adjusted one with reference to the other, as well as affording an adjustment of both of them to various points along the spind le While a given space between them is maintained. Moreover, it will be seen that each is reversible on the supporting spindle, so that the gages may be arranged with their hubs extending towards each other, as shown, or one extending outward to the left, or both extending inward to the right, or where the gages are to be brought in close relationship the hubs may extend away from each other, giving the closest possible arrangement '0 the plate-like gages 61, 62.

Aside from the side edge paper gages described above, it should be understood that suitable paper end stops, such, for example, as certain of the end stops described in the patent to C. E. Burns, No. 1,647,854, may be employed. However, since a specific description of such end stops is'unnecessary to arrive at an understanding of the present invention, further reference thereto will be omitted.

In addition to the feed rollers 42 I provide two sets of marginal paper feed rollers, an inner set 65 and an outer set 66, arranged above the printing line, and means are employed for controlling said feed rollers and also for automatically controlling other devices in the machine as disclosed in my original application, Serial No. 143,382. A showing of such construction is, however, unnecessary in the present case and I have, therefore, merely diagrammatically represented such additional feed rollers in Fig. 1, as indicated at 65 and 66.

Assume that a register sheet R (Fig. 8) and its accompanying carbon sheet (not shown) have been introduced through the channel 20 and properly positioned with the leading edges thereof beneath their feed rollers 42. The operator then introduces a ledger sheet L from the front of the platen into the channel 19 and accurately positions said sheet. The outer feed rollers 66 are then caused to bear against the platen and against the margins of the previously introduced ledger sheet. The statement sheet S with an accompanying carbon sheet (the latter not being shown) may then be introduced from the front of the platen into the channel 19, and between a second inner set of feed rollers 65 and the platen, or the ledger sheet thereon. After the statement sheet and the accompanying carbon sheet have been properly adjusted. the said second set of feed rollers 65 is applied to thepreviously adjusted statement sheet S. The machine is then conditioned to proceed with the writing, and the I matterwritten will be produced on the statement sheet and-through the carbon sheets on I the ledger and register sheets.

cumulation of the various statements to be written, and a corresponding carbon sheet (having its-effect ve face'next to the register sheet) are, as indicated above,first introducedtogether from the rear of the platen through the channel 20, being positioned widt-hwise with the aid, say, of the side/edge gage 61-; The leading ends of the register and its carbon sheet are then introduced beneath the paperfeed rollers 42 and the sheets are adjusted to proper position in a line feed direction. After initially positioning the register sheet in the manner indicated, no further attention need be'paid to it in the successive introduction, writing and withdrawal' ofthe different statement and ledger 7 thus introduced may be properly positioned sheets. Theregister and associate carbon sheet having been initially positioned as in dicated, a: ledgersheet carrying the account of the statement to be written is introduced fromin front of the platen through the chan nel 19, with the aid of the deflector ll' inthe dotted line Fig.1 position. The ledger sheet widthwise of the machine and theregister sheet, with the'aid of the side. edge gage 62.

'Theoperator-then positions. the outer set of feed rollers66 to clamp the ledger sheet against the platen and introduces the statement sheet S rearward through the channel 19'with the aid of the deflector 41. v The second inner'set of feed rollers is then moved to efiective' position to clamp the statement sheet against the platen. The operator may now proceed to write the statement and simultaneously produce a manifold? copy thereof in requisite positions on the ledger and.

register sheets. It will be understoodthat after Writing each statement the carriage is; automatically returned and the platen I automaticallyline spaced, thereby spacing the platen 'to bring the register sheet in proper position to receive 'a manifold copy ofthe next'statement written on the machine.

, In, substantially the same manner as that indicated above themachine maybeemployed as ;a check writing machine, at which time the sheet described above as a register sheet would constitute a manifold record Votthc checks written and may constitute a pay roll sheet Inthis event, however, no ledger sheet willbe'employed. The outer set of feed rollers 66 will be employed to coact'with by LettersP-atent, is

V e' 'Generally speaking, the sheet described above as a register sheet, andwhich'remains in the machine when the other sheets are rcmovedjand new ones inserted, may constitute a register sheet, a proof sheet, a sales sheet, a distributing sheet, or a payroll sheet, dependingon the use of the machine for different purposes.

combined work sheet guiding and supporting. members' having curved working faces con: tained within saidychannel, said members being secured to the lower deflector and free from contact with the upper deflector and spaced apart to afford free passage of a worksheet through the channel beneath another work sheet supported by'said supporting'mcmbers, means that enable said work" sheetsupporting'members to receive a relative'adjustment longitudinally of the platen in order to vary thespace between them, and a thlrd paper; deflector movable from an neffective position where it crosses the pr nting line and aids'in directing work sheetsrearwardly into'said channel.- 7

12. In a typcwritfng machine, the comblnation of a carriage, a cylindrical platen carried thereb a :1 )er deflector which extends around beneath the platenand is mounted for movement towards and away from the platen, a spring which tendsto force the deflector toward the platen, and adjustable means for limiting the extent of movement of the'deflectortowards the platen under the force exerted on the deflector bysaid spring. "13. In a typewriting or like machine, the

' combination of a, carriage, a platen carried thereby, two curved pa er deflectors arranged one above the other and extending beneath the platen, means for maintaining said deflectors spaced apart so that they with the platen will formtwoseparated channels through which work sheets may pass, one of said channels being between the platen and the upper deflector,the other channel being between the two deflectors, said curved deflectors being pivot-ally supported on the carriage so that the forward edge of the upper deflector may bear lightly against the platen, a spring'for movingthe deflectors on their pivot towards the platen-v and adjustable means forlimitingithe pivotal movement of said paper deflectors towards the platen.

'14. In a typewriting or like machine, the comb1n'at1on of a.carr1age, a platen carried thereby, .two curved paper deflectors arranged one above the other and'extending beneath the platen, means for maintaining saiddeflectors spaced apart so that they with the platen will form two separated channels through which work sheets may pass, oneof said channels being between the platen and between the two deflectors, said curved deflectors being pivotally supported on the car- I riage'so that the vforward edge of the upper ,means for limitingthe pivotal movement of deflector may-bear lightly against the platen, adjustable means for limiting the: pivotal movement of said paper deflectors towards the platen, and independently adjustablesaid paper deflectors away from the platen. 15. In a typewriting machine, the combi-,

nation of a carriage,'a cylindrical platen carried thereby, a paper deflector which extends around beneath the platen and is mounted for {movement towards and awe from'the platen, a snail cam-against whici said deflector normallybears to limit the movement of the deflector towards the platen,

and means for enabling said cam to receive 7 a rotative adjustment to and for holding it in, difl'erent set positions 16. In a typewriting machine, thecombi' nation of a carriage, a cylindrical platen carried' thereby, a paper deflector which extends around beneath the platen and is mounted for movement towards and away from the platen,"a snail cam against which saiddee flector normally bears to limit the movement of the deflector towards the platen, means for enabling said cam to receive a rotative adjustment to and for holding it in different set positions, and a corresponding independently adjustably snail camnormally u out of'c'ontact with said deflectorv and with which the deflector coact-s to limit the motion of the deflector away from the platen.

17. In a typewriting or like machine, the combination of a cylindrical platen, a curved paper deflector beneath the platen, and a plurality of separated combined work sheet supporting and guiding devices projecting from the contactface of said deflector and having a contact face extending longitudinally. in the direction of the line feed of the work sheets for supporting and guiding one work sheet off the contact face of the deflector and thus provide an unobstructed space between said combined supporting and guiding de- 1.1L,- sage therethrough while another narrower work sheet may be introduced andfreely fed through said channel between said supporting devices, a set of feed rollers which coact with said narrower work sheet while theelatter extends into said channel, a secondset of feed rollers ooacting with the wider sheet while the latter extends into said channel, and a third set of feed rollers out of cooperative relation with said relatively wide and narrow'work sheets and coacting only witha register sheetintroducedbetween the upper- I most of said'pair of'guiding devices and the platen and effective to hold said register sheet against accidental displacement while the other sheets are being inserted in or removed from said channel.

19. In a typewriting or like machine, the combination of a platen, a set of paper feed rollers, a spindle on which said feed rollers are mounted, and a plurality of side edge paper gages mounted on and adjustable along said spindle one independently of another to different set positions, each of said gages being reversible on said spindle, and provided with a hub ofi-set to one side thereof, the reversibility of the gages on the spindle enabling the gages to be brought close together on the spindle when desired.
